A bookkeeper has a balance of $83.92. If she collects $76.75
kotegsom [21]

Answer:

The bookkeeper already has a balance of 83.92.  She collects 76.75 so that's 83.92+76.75 which equals to 160.67.  Then she pays out 38.58 so that's a deduction to what she already has.  160.67-38.58=122.09.

SO the bookkeeper has $122.09 left.

algol [13]

Answer:

7/24

Step-by-step explanation:

Let

total items barbequed = 1

Veggie burgers = 3/8

Corn cobs =1/3

Mushroom caps = x

Veggie burgers + corn cobs + x = 1

3/8 + 1/3 + x = 1

9+8 /24 + x = 1

17/24 + x = 1

x= 1 - 17/24

=24-17 /24

= 7/24

x = 7/24

Fraction of barbequed items that are mushroom's is 7/24
